I know wishing for the return of Tony Adams is foolish but you'd bite off your right leg for the return of the donkey. A couple of things you could say about Adams was that he at least knew how to defend and he would put his body on the line for his team. The only thing Mertesacker is sure to do is pick up his paycheck at the end of the week. What a complete waste of money he is.
To think that he was once Germany's starting centerback, I wouldn't give him a game on the local pub team. He is slow, ponderous and seemingly has no idea how to sense danger, the prime requisite of any defender.
Wenger in his desperation to fill the role bought second hand goods. The days of the famed Arsenal back four that George Graham created and Arsene Wenger perfected has been consigned to the attic where dust and mites can grow old together.
